Part(s) Affected

Blue iQ® Fault Code 7265

Title
Gaseous Fuel High Pressure Shutoff Valve - Data Valid But Below Normal Operating
Range - Moderately Severe Level
supply solenoid valve (SSV)

Diagnostic Overview
Fault Code 7265 is a fault triggered when the Blue iQ® Fuel System Control Module (FSCM) detects supply
solenoid valve (SSV) resistance:
a) below 2.5 ohms for more than 0.4 seconds - 12V SSV
OR
b) below 15 ohms for more than 0.4 seconds - 24V SSV
This fault is typically accompanied by the following symptoms:
1.
Ignition On, Engine Off – Low-pressure gauge reads 0 psi / kPa
2.
Ignition On, Engine Off – Supply solenoid valve does not “click”
The integrated SSV coil used on the Hexagon Agility Marathon extended range
pressure regulator possesses a different resistance at temperature range than the
standalone SSV coil used on standard pressure regulators. Before proceeding
with this procedure, please contact Hexagon Agility Technical Support for a
resistance at temperature chart for the integrated SSV coil.

Warning Statements Used in this Procedure
NOTICE is used to address practices not related to physical injury, such as best
practices or tips to help an operation or procedure go smoothly and prevent equipment
damage.
WARNING indicates a hazardous situation which, if not avoided, could result in death
or serious injury.

Tools Required
Item

Purpose

digital multimeter (DMM)

resistance and voltage measurements

J1939 OBD-II diagnostic interface

connect vehicle to Cummins® INSITE™ on PC

Cummins® INSITE™

diagnostic software

1 of 5

Perform Initial Vehicle Check procedure (refer to DSM.0009) prior to performing
diagnostic instructions listed below.

Circuit / System Verification
1. Connect the Cummins® INSITE™ diagnostic tool to the vehicle and navigate to the “Agility® Fuel Delivery
System, CM1881 AFS(18)”.
2. Record all active and stored fault codes and parameters prior to clearing fault codes using INSITE™.
3. Observe and record Gaseous Fuel High Pressure Shutoff Valve data from INSITE™—is data within
reasonable operating range?
a. If not within range proceed to Circuit/System Testing.
b. If within range proceed to Step 4.
4. Operate the vehicle in the same conditions for enabling the fault code or within the same conditions that
triggered the fault code based on recorded data.
5. Verify that the fault code does not set. If any fault code sets proceed to Circuit/System Testing.
6. While observing Gaseous Fuel High Pressure Shutoff Valve parameters in INSITE™ perform a wiggle
test on the harness and connectors to test for poor or intermittent connections.
a. If any fault code sets, proceed to Circuit/System Testing.
b. If no fault code sets, system is functioning to design intent.

Reassembly and Validation
After completing all repairs, always perform the following steps to confirm the issue is fixed:
1. Reconnect all connectors and verify connections are secure.
2. Reattach any enclosure covers and close any fuel system doors.
3. Clear fault codes using Cummins® INSITE™ tool.
4. Run vehicle until it reaches normal operating temperature. Refer to OEM instructions.
5. If fault is cleared, return vehicle to duty.
If fault is not cleared, contact Hexagon Agility® Customer Care and Technical Services.
